baro

Type a goal in your repo. Walk away. Come back to a verified pull request.

baro is an autonomous software factory. It compiles your goal into a machine-checkable contract, splits it into a DAG of stories, builds them in parallel across isolated git worktrees, and blocks every merge behind fail-closed gates — declared tests, build, an evidence critic, write-surface ownership. You review a PR the gates already accepted.

One prompt → a 33-story plan → 808 passing tests → a PR, in 71 minutes. See a real run.

Install

npm install -g baro-ai

Needs Node 20+, git, and at least one backend: the claude CLI (default), codex, or any OpenAI-compatible endpoint. baro --doctor checks your setup.

Use

cd your-repo
baro "Add JWT authentication with role-based access control"

That opens the TUI: intake asks only what matters, you confirm the plan, the fleet runs.

For automation, detach and follow from anywhere:

baro --headless --detach --goal-file goal.txt   # prints a run id, returns immediately
baro watch <run-id>                             # follow milestone events
baro logs <run-id> --follow                     # tail the raw log
baro runs                                       # list live runs
baro stop <run-id>                              # stop one

Commands

Command	What it does
baro "<goal>"	run a goal in the current repo (TUI)
baro --goal-file <path>	read the goal from a file
baro --headless --detach ...	background run for CI/automation; prints the run id
baro watch <run-id>	follow a live run's milestones
baro logs <run-id> [--follow]	print or tail a run's log
baro runs / baro stop <id>	list / stop live runs
baro --resume	resume an interrupted run from prd.json — never re-plans
baro --continue	follow-up on the current branch — always re-plans
baro --doctor	self-diagnostic: backends, auth, gh, permissions
baro login	browser sign-in for baro cloud
baro connect [--install-service]	attach this machine as a cloud runner

The flags that matter

--llm claude|codex|openai|opencode|pi|hybrid|jigjoy   # backend for all phases
-m opus|sonnet|haiku          # model override (verbatim pass-through on other backends)
--effort low..max             # thinking per turn (default: high)
--parallel N                  # max parallel story agents (0 = unlimited)
--mode focused|sequential|parallel   # force an execution mode (default: intake proposes)
--quick                       # trivial goals: one story, no architect/critic/surgeon
--local-only                  # no pushes, no PRs — hard isolation
--shell-budget <seconds>      # per-command budget for story shell tools
--openai-base-url <url>       # any OpenAI-compatible provider (OpenRouter, vLLM, Ollama…)
--tier-map "light=openai:MiniMax-M3,heavy=claude:opus"   # mix backends per story tier

Per-phase overrides (--architect-llm, --story-model, …), .barorc, and everything else: docs.baro.rs

How it works

• Contract first. An architect turns the goal into invariants and obligations that are machine-checkable — before any code is written.
• A collective, not a coordinator. Story agents are peers on an event bus: they see the events that concern them, exchange notes, and suspend/resume on each other's work. There is no single context window everything must squeeze through.
• Gates, not vibes. Declared tests, build-before-commit, an evidence critic that judges captured command output, and write-surface ownership — fail-closed, blocking every merge. The human reviews a PR the gates already accepted.
• A live plan. The plan is a DAG the run negotiates with: runtime replanning adds and rewires stories mid-run, and a failed gate can spawn its own remediation story.

Drive it with Claude Code

baro pairs well with a coding agent in the driver's seat. Paste this into Claude Code inside your repo:

Install baro (npm install -g baro-ai) and run `baro --doctor` to verify the setup.
Then drive it for me:

1. Write my task as an evidence-rich goal file: name the exact files and line numbers
   the change touches, state the constraints, and say which tests must prove it.
2. Launch it detached: `baro --headless --detach --goal-file goal.txt`, note the run id.
3. Follow it with `baro watch <run-id>`; if it stalls, read `baro logs <run-id>`.
4. When the pull request opens, review the diff against the goal, run the project's
   test suite yourself, and report back: what shipped, what the gates proved, and
   anything that needs my eyes. Merge only if everything is green.

Keep goals narrow — one concern per run. If the run fails, read why, tighten the goal
with the new evidence, and launch again.

Cloud

No machine, or no Claude/Codex subscription? Run the same fleet on app.baro.jigjoy.ai — nothing to install, isolated sandboxes, our keys. Or keep your own hardware in the pool: baro login, then baro connect --install-service.
